I tried using eucalyptus oil scent in my bedroom. I have not noticed any difference. Get the doctor to get you a sample inhaler to carry for your Mom.

does your mother have a milk allergy? Please read the paper included in the package

Hey Doris, thanks for you reply. Have you found any natural things that have been helpful?
Also, for the Eucalyptus, did you try it with an atomizer diffuser? I've been doing some research and I thought a regular vaporizer would work. Not so. Should be an atomizer. Anyways, curious if you found anything else that has worked ( in addition to the inhalers). Thanks!!
